some of the lights in stores say "promotes invertebrate growth" if we have
crabs/crayfish/shrimp do we need a special spectrum?

I would assume they were talking about corals.

Also, exactly how does the
mostly red light look, if it gives a weird "satan tank" look to the thing
then I'd rather have algae :-P

LOL! There is that....
